Plasma screening and nonideal collective effects on the electron-impactexcitation of hydrogen-like ions are investigated in nonideal plasmas. Theinteraction potential in nonideal plasmas is given by the pseudopotential model,taking into account the screening effect as well as the collective effect.The screened radial atomic wavefunctions and energy eigenvalues for the1s and 2p states of the hydrogen-like target ions in nonideal plasmasare obtained by the variational principle and perturbational method.The analytic form of the screened Coulomb focusing factor is obtained,including the plasma screening and nonideal collective effects in order toinvestigate the correct behaviour of the excitation cross section near theexcitation threshold. The excitation cross section including the screening,collective, and Coulomb focusing effects are obtained as a function ofthe nonideality plasma parameter, Debye length and kinetic energy ofthe projectile electron. It is found that the scaled 1s → 2pexcitation cross sections including the plasma screening and collective effectsare found to decrease with increasing the nonideality plasma parameter.
